Example: Step Down Transformer

Problem Statement

Given a 48 kVA, 480/240 V/V step down transformer operating at rated load with a power factor of 0.7 (lag), determine the efficiency and voltage regulation.

Given: $R_{L} = 0.2 Ω, X_{L} = 0.6 Ω, R_{H} = 0.8 Ω, X_{H} = 1.6 Ω, R_{c H} = 3.2 k Ω, H_{c H} = 1.2 k Ω$
